Definitions

  • Powder materials of 56.74 percent by weight of SiO 2 , 10.42 percent by weight of MgO, 25.33 percent by weight of Al 2 O 3 and 7.51 percent by weight of Si 3 N 4 were employed as glass raw materials. A mixture of these raw materials was melted and refined under a nitrogen atmosphere at 1700 °C for 5 hours and at 1600 °C for 3 hours respectively. This glass was cooled and thereafter partially drawn out, to be subjected to measurement of transmittance. Fig. 1 shows the result.
  • Raw materials of 50.31 percent by weight of SiO 2 , 9.81 percent by weight of CaO, 11.54 percent by weight of MgO, 20.83 percent by weight of Al 2 O 3 and 7.51 percent by weight of Si 3 N 4 were employed as glass raw materials. 1 kg of a mixture of these raw materials was melted and refined at 1650 °C through a carbon crucible of 14 cm by 10 cm by 10 cm which was lined with BN, under an atmosphere containing Ar and N 2 in a ratio of 1:9. The melting and refining times were varied to count the number of Si particles contained in the glass by the following method. Table 1 shows the results.
